Last week I got four, four day old chicks, two australorps and two rhode island reds. A few days ago one of the australorps died so we replaced it with another australorp, from the same hatch. When first introduced, they seemed fine, not hassling her or picking on her. Now, it seems the biggest RIR (the bully) has decided she is good to peck. She and the other RIR are pecking her and picking on her, they have drawn a little bit of blood. Now, I can separate her but what are the chances of her then being able to be integrated back with the others? Obviously I dont want to be keeping a single bird away from the others, by herself. Or, I can leave her with the others, are they likely to take it to an extreme level and really hurt her? I've experienced pecking and cannibalism before but only in mature birds, layers, not such young chicks. Or, I wondered if I should put her and the other australorp into a separate brooder, let them buddy up, and introduce the two pairs back together?
